1 Be it known that I, G TTHILELEECHAEB, a citizen of the United States, resid ga Megargel, in the countyof Archer and State of Texas, have invented certain new and useful Improvements in'Tire-Tighteners of which the following is a specification, reference being. had to the. accompanying drawings; V p p My-lnvent on relatesto 1-neans..f0r com- 'PQIISMFIDg for the relative expansion and contraction of the tires and fellies of vehicle wheels.

The primary object of my invention is the provision {of a" very simple and easily operated means wherebytires may be contracted upon the felly of a-vehic-le wheel or expanded with relation thereto.

A further object of theinvention is to provide a split tire with means connecting the ends of the tire whereby the-tire may be contracted to anydesi-red extent, and in this connection to provide a filling piece adapted to be disposed between the confronting ends of the tire and locked firmly in position against movement in any direction when the tire is-contracted upon the felly. I r

A further object'of the invention is to' provide the confronting ends of the-felly withiboxes or ferruleswhich act to prevent the splittingoftheends of the "felly and to "also receive and to a cert-ainextent support the extremities of the expanding and contracting screw.

Still: another object of the inventionis to provide a tire tightener so. constructed that allof the parts are entirely housed and protected-when in use, the'constrnction being such, however, as willpermit ready access to the tightener itself at any time desired without the necessity of removing any part and the consequent liability of its being lost.

Other objects will be more fully brought out in the following specification.

-My invent-ion'is illustrated in theacconipanying drawings, wherein Figure 1 is a front elevation of a wheel constructed in accordance with myinvention; Fig.2 is an enlarged longitudinal fragmentary section of the tire and felly of the wheel; Fig. 3 is a fragmentary side elevation of the tire and a portion of the felly with one of the sliding plates. opened;

Surroundingthe felly a tire 6. This tire is eitherinade'in one section splitat we. p int f a plural y f s ct o a I do not wish to be limited in this matter. 7

A ssim ing that the tire is made in two sec t ons and that the felly is. also madein two sections, theneach section 6. of the tire is --provided, at its ends with the inwardly fdirected abutments 7, each of theseabutmerits being. longitudinally screw threaded throughout its entire length.

- )Disposed bet veen-each pa r of abutments threaded engagementwith the ahutments 7 isuthe adjusting screw 8. This screw isgy't c provided at its middle with a many-sided head 9 and is reversely threaded at opposite .ends -The adjusting screw 8 has screw-- andjasa consequence when the screwS is rotated in one direction, the abutments will beforced apart,and when the screw 8 is rotated in the othendirect-iontheabutinents will he --drawn toward each other. The

confronting ends of the tire sections are beveled lnwardand toward each other as at.

11, andeach beveled face is formed with a medially d sposed groove 12 which is in clined' rever'sely to the inclinationof the face 11.

Disposed between theconfronting ends of the tire sectionsare. the-"filling pieces- 18 whieh are substantially arcuate in form.

vided with the projecting tongues 14 which are beveled so as to fit within the grooves 12.

It will thus be seen that when the filling abutments'? are preferably made integral; with the tire sections 6 and each abutment is pieces are in place they are locked from lateral movement and from movement radially either inward or outward. I

Riveted, bolted, or otherwise attached to the opposed ends of the felly sections 5 are the ferrules or boxes 15. These form caps upon the ends of the felly sections which prevents the ends of the felly sections from splitting under strain. The transverse web of each cap or ferrule is formed with an opening 16 through which the ends of the adjusting screw 8 project, and rest, as will be seen from Fig. 2. The extremities of the screw 8 project about a quarter of an inch into the'confronting ends of the felly sections.

'For the purpose of inclosing andhousing the tire adjusting mechanism, and also for the purpose of locking the screw 8 in its adjusted position, I provide the side plates 17. Theseplates are arcuate in form and are disposed one on each side of the 'felly at the gap between the fellysections. Each plate 17 at one end is formed with a'slot 18 and at its oppositeend with aslit 19 opening above the extremity of the plate 17.

The'felly sections are provided adjacent their confronting ends with theheaded pins 20. One of these pins passes through the slot 18, while the other pin on the opposite felly section is engaged by the slit 19 when the plates are arranged in alinement with the. felly. The pins 20 are preferably formed by bolts which pass through the folly sections and are provided upon their extremities with nuts. This eliminates the necessity of'removing the bolts 20 in order to shift the plates 17 out of the way. It is only necessary to loosen the bolts '20 so as to permit the plates 17 to be shifted in one direction and then allow themto drop down into the position shown in Fig." Thus ready access may be, had to the adjusting screw 8 so as to permit the application of a wrench to the head 9 whereby the screw may be turned. p

In order to prevent the accidental rotation of the screw 8 I provide means whereby vious, therefore, that when the side plates 17 I this screw is locked from rotation and to this end I provide the side plates 17 each with a bolt-hole 21 through which a bolt 22 passes,

this bolt being so disposed as to engage with one of the facets of the head 9. It is ob- Copies of this patent may be obtained for are in their closed position and the bolt 22 spokes, whereas by tightening the tire as the felly shrinks, the felly may be far more firmly forced down upon the spokes. It will furthermore be seen that the screw 8 is not subjected to shocks as it would be were this screw abutted against the folly sections, and did this screw sustain the strain of holding the felly sections apart or expanded against the tire. The compressive strain exerted upon the wheel is received by the filling piece 13, and thus there is no danger of the screw 8 being bent or otherwise damaged.

iVhile I have illustrated what I believe to be the best form of my invention, I do not wish to be limited to the details of construction, as it is obvious that many changes might be made without departing from the spirit of the invention.

-Having describedmy invention, what I claim is:

The combination with'a split felly, of v having their end walls beveled in a direction.

opposite to the beveled faces of the extensions, a filling piece disposed between the extensions having'its opposite ends beveled to correspond to the beveled faces of the eXtensions, beveled tongues formed upon the ends of the filling piece having engagement within the recesses on the extensions.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
